Question

I’m sure someone knows this and I will be very thankful for the answer. I don’t know much about delegates and asynch and the like – so please give me a general example of how I could implement.

I have a workflow where
I can use Parallel.Foreach to execute a method for many different files at the same time (sweet, grind that processor) –
however after that method ends I need to run another method (it generates a report on the previous process),
and this second method cannot be run in parallel.

I don’t want to wait for all the files in the Parallel.ForEach to finish before generating reports (that’s not necessary). But if I start the report generation method as the first method ends then I run into problems. Is there some kind of queue or something? There’s gotta be some pretty way of doing it, right?

Thanks

I think what Jim G means is:

var lockObj = new object();

Parallel.Foreach(files, file => 
{
    // Processing file
    lock(lockObj)
    {
        // Generate report.
    }
});
